Okay so I lost my virginity on January 6, 2017. I was dumb enough to not make him wear a condom... he pulled out and said he didn't come in me but I can't seem to trust that. I don't have any pregnancy symptoms other than feeling tired. I've also had a lot of gas. My concern is that my periods have came on a 26 day cycle each month since then, but they're a lot lighter than normal! I hear people can still have a period and be pregnant but I've had 5 negative pregnancy test. I've always had OCD and anxiety. Do you think that the stress and anxiety is causing this change in my period? All it does is make me even more worried!
